At the end of prints I get "Unloading Filament" "Ramming" and stuck at 50%.
Every 2 or 3 prints when using the MMU3, It gets stuck like this indefinitely. The filament seems to be retracted just fine, if I reset the machine it prints again just fine as well. Not a huge issue, but still an inconvenience. Any ideas? I imagine maybe a sensor isn't calibrated quite right?

This exact thing keeps happening to me too.
Any updates?

What version of firmware are you using? 6.4.0 has been known to cause errors like this. I reverted to version 6.2.6, and those errors went away.
MK4S/MMU3
RE:
The older image above shows a typical FINDA adjustment error. Look closely at the sensor states on the bottom row. Do you see that even though the filament is pulled all the way past the MMU feed roller, FINDA reports ON as if filament is present in the bowden! Instead of uploading the firmware, carefully recheck and calibrate FINDA!
